Description

A supporting and connecting device for prefabricated wall panel of prefabricated
structure
TECHNICAL FIELD
The invention relates to the technical field of building production, in particular to a
prefabricated wall panel support and connection device with a prefabricated structure.
BACKGROUND
Prefabricated building has the advantages of fast construction progress, short
construction period, labor saving and so on. At the same time, the construction site has less
noise and less waste, which is conducive to energy conservation and environmental
protection and promotes the transformation and upgrading of the construction industry. It
has been widely used in the engineering field. In the construction of prefabricated
residential buildings, the installation of prefabricated wallboard needs to be fixed with
inclined support. During the installation of prefabricated wallboard, the external wall must
be vertical to the floor slab, and no toppling or tilting back is allowed. However, in the
actual construction process, due to the construction error or the influence of strong wind
load such as super high-rise building, it is difficult to keep the precast wallboard vertical,
which requires that the diagonal bracing must be fixed reliably with sufficient adjustment
function.
At present, the common inclined support is usually composed of adjusting screw,
upper anchor plate and lower anchor plate. The upper end of adjusting screw is fastened by
the pre-embedded anchor nail in upper anchor plate and prefabricated wall plate. The
installation of oblique support for prefabricated wallboard often causes that the positioning deviation between the anchor plate and the reserved bolt on the cast-in-situ base plate is too large and the adjustment function of the adjusting screw can not be compensated and the connection can not be realized. If the deviation is corrected by re-drilling and pre burying or adopting the post-anchoring expansion bolt, it may lead to the phenomenon that the bolt falls off the base plate due to insufficient strength, and the adjustment of the adjusting screw is not easy to control, but also manual fixing and time-consuming and laborious, so a kind of supporting and connecting device for prefabricated prefabricated structural prefabricated wall panel is needed.

DESCRIPTION OF THE INVENTION
The technical solutions in the embodiments of the invention will be described clearly
and completely in combination with the drawings in the embodiments of the invention.
Obviously, the described embodiments are only part of the embodiments of the invention,
not all of them. Based on the embodiments in the invention, all other embodiments obtained
by ordinary technicians in the art without making creative work belong to the protection
scope of the invention.
In order to make the above objects, features and advantages of the invention more
obvious and easy to understand, the invention will be further described in detail in
combination with the drawings and the specific implementation mode.
As shown in Figure 1-Figure 3, the invention provides a supporting and connecting
device for prefabricated wall panel of prefabricated structure.
The device comprises a stable structure fixedly arranged on the prefabricated wall panel, a
bracket (1) fixedly arranged on the ground and a support rod (2) arranged between the
stable structure and the bracket (1). The bracket (1) is hinged with the support rod (2).
The stable structure comprises a base (31), wherein an installation rotary table (32) is
fixedly connected to the base (31), and a housing (41) is detachably connected to the outer
side of the installation rotary table (32). The turntable (32) is provided with at least two
sets of grooves (33), a rack (34) is arranged in the grooves, a plurality of groups of springs
(35) are fixedly arranged between the rack (34) and the bottom of the groove (33), and
downward-facing serrations (36) are arranged on the rack (34).
A lifting plate (42) engaged with the rack (34) is arranged inside the housing (41), and
opposite serrations (36) are arranged on the contact surface between the lifting plate (42) and the rack (34). Guide rails (43) are arranged on both sides of the front and rear end faces of the lifting plate (42), and sliding grooves (47) matched with the guide rails (43) are arranged on the turntable (32) and the housing (41). The lifting plate (42) is provided with a chute (44), the top of the inner wall of the chute (44) is provided with a plurality of groups of positioning holes, a slider (45) is slidably arranged inside the chute (44), a positioning block matched with the positioning holes is fixedly arranged on the slider (45), and a sleeve rod (46) is hinged on the slider (45). The sleeve rod (46) is arranged on the outer side of the support rod (2), and the two are detachably connected by a bolt.
As a further optimization scheme, the rack (34) is internally provided with a plurality
of spring holes, the spring (35) is arranged in the spring hole of the rack (34), and one end
of the saw tooth (36) of the rack (34) extends out of the groove (33) under the normal state.
The base (31) is a rectangular structure, four mounting holes are arranged on the four
corners of the base (31), and the prefabricated wall panel is fixedly connected with the base
(31) by bolts.
In the working process, the prefabricated wall panel and the base (31) are fixed and
connected by bolts, the support rod is hinged with the support, the position of the slider
(45) is adjusted so that the sleeve rod (46) and the support rod (2) are on the same horizontal
line, the sleeve rod (46) and the support rod (2) are connected by bolts, and the position of
the slider (45) is adjusted again so that the support rod forms a support for the slider;
secondly, by pressing the support rod downward, the slider (45) moves downward with the
support rod. The movable lifting plate (42) moves downward along the chute (44). Because
the rack (34) and the saw tooth (36) on the lifting plate mesh with each other, and the rack
restricts the lifting plate to move downward only. When the supporting effect of the supporting rod on the prefabricated wall plate meets the requirements, that is, the prefabricated wall plate is in a vertical state, and the supporting rod stops pressing downward. At this time, the supporting rod reaches a locked state, and the stability can be improved.
In the description of the invention, it should be understood that the orientation or
position relationship indicated by the terms "longitudinal", "transverse", "up", "down",
"front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside"
is based on the orientation or position relationship shown in the drawings, only for the
convenience of describing the invention, Rather than indicating or implying that the device
or element referred to must have a specific orientation, be constructed and operated in a
specific orientation, it cannot be understood as a limitation of the invention.
The above-mentioned embodiments only describe the preferred mode of the invention,
not limit the scope of the invention. On the premise of not departing from the design spirit
of the invention, all kinds of deformation and improvement made by ordinary technicians
in the field on the technical scheme of the invention shall fall into the protection scope
determined by the claims of the invention.
